GLS is technology-flexible. We select and integrate treatment processes based on water characteristics, quality requirements, site constraints and lifecycle performance. The technology should serve the solution — not the other way around.
Reverse osmosis removes dissolved salts and other contaminants by applying pressure across a semi-permeable membrane.
Our RO systems can include pretreatment, pressurization, membrane arrays, instrumentation, cleaning systems and post-treatment.
Ultrafiltration is used for drinking-water production, industrial treatment, reverse-osmosis pretreatment and tertiary wastewater treatment.
GLS UF packages combine high-quality membrane filtration with compact system design and efficient operation.
MBR systems separate treated water from activated sludge through ultrafiltration membranes rather than conventional settling.
DAF uses microscopic air bubbles to lift contaminants to the surface for skimming.
GLS supplies screening and filtration technologies for different stages of the treatment process.
The correct combination helps remove solids, protect pumps and membranes, reduce fouling and stabilize downstream performance.
Activated Filter Media is designed as a direct alternative to conventional sand media.
GLS is an authorized distributor of Activated Filter Media in Indonesia.
GLS supplies and fabricates process vessels including decanter tanks, mixing tanks, chemical-storage tanks and degasifiers/aeration towers.
Systems are available in different sizes and materials and can be customized to the process, chemical compatibility and site layout.
Our thickening and dewatering technologies are designed for straightforward installation, reliable operation and simplified maintenance.
They support municipal and industrial facilities seeking cleaner, more efficient sludge handling.
GLS supplies pumps and replacement parts for water movement, pressure and process applications. Our diffuser systems support efficient oxygen transfer in biological wastewater treatment. Static mixers blend chemicals and process streams without moving parts, providing reliable mixing with compact installation requirements.
Our engineers help ensure each component is correctly sized and compatible with the complete treatment system.
